Application filed February 27, 1911. Serial 1705611355.

Toull 'wfiom z'tmay concern Be it known that LBERNARD T. Lnvnonn,

a subject of the King of=Great Britain; and

resident of Boston, county of Sufiol-k, State Y. ment of the. buttons, the time and ,labor re i quired-toperform the operation are reducedof Massachusetts, have invented an Improvement in Buttonhole andButton Location Marking Machines, of which the fol lowing description, in connection with the accompanying drawing, is a specification, the drawing repres'ent1ng like characters on like parts.

This-invention has for its object the -.production of an improved machine for ;mark' p .ing on leather-or other fabric the exact-location *for a set of buttonholesor buttons,- :whereby in subsequent operations, such the making of the buttonholes or, the attachvery ma'teriallyand the buttonsor button-.

.holes are accurately positioned upon the work and correctly spaced.

My invention is particularly adapted-for. "marking the location for a set of-'buttonholes on the buttonhole strip "of a shoe,;and I have so .constructed; and arranged-athe mechanism that when the marking deviceshave been properly set or adjusted for either a right or a left set the other set can be marked by a simple reversal/of the head which carries the marking devices.

In the ;present embodiment :of my invention the marking members are individually adjustable both laterally and in and ,out'

with relation to the head which supports them, so that any'desired arrangement or' location of the positions -to be markedcan be made.

The various novel features o'fvmy lnven- 'tion will be-fully described in the subjoined specification and particularly .pointed out in the following claims. I

.Figure 1 is a top plan view of'the marking machine embodying one form of. my present invention, showing the set or series of marking devices in adjusted position. to mark a left-hand buttonhole strip; Fig.2

is a longitudinal section thereof the greaterpart of which is taken .on the line 272, Fig. 1, looking toward the left, withs the machine. at rest and in readiness to beqset in operation, the "clutch at the right hand side of the base being shown in section; 3'is "a similar view but vshowing the marking devices in cooperation -with "the work tov mark 'the desired locations thereon Flg. 41s a transverse sectional detail, on the line 4-4, Fig. 1, and partly in section, of

the means -for clamping the head in the carr1er;-F1g. 5 is-a detail in elevation and part section on the --line 5-5, Fig. 1, through one .oftheclampingseats shown in Fig. 4; Fig.

one. of the marking devices, on the "line:

10-10, Fig. 1.

In Figs. 1, 2 and 3 of the drawing 1 is a cast-iron or othersuitable base, tosustain the operative parts of-the machine, the front of the flat-top-2 havinga rectangulantransversely extended raised portion 3 on which is fixedly mounted a flat work-bed 4, preferably a piece of thick leather.

At the back of the base ears 5 on the :top

Q'fOrmbea-rings for a transverse rock-shaft 6 attached to the rear end of a yoke-like carrier-comprising divergent arms 7 and a connecting cross-plate 8 at the front ends thereof, the front end of the carrier beinga short distance behind the work-bed and fulcrumed in parallelism therewith. I

The front and separated ends of the carrier arms are shaped to present two parallel split hubs 9 constituting contractile. seats, the opposite sides of each seat having upright tubular ears 10, 11, the bores of saidear-s being alined transversely of.the base 1 and at right angles to the axes of the seats 9, as shown in Figs. 1 and 4, the outer ears 10 being tapped to present'right and left hand threads. 7

A two-part controlling rod 12 fixedly connected centrallyv by a split sleeve 13 clamped to the inner ends of the two parts, as shown in Fig.v 4:, the outer ends of said parts passing loosely through the ears 11 and at their extremities threads engage the I ears. 10. Collars l tfixed on the-controlling rod just inside the ears 11 prevent longi-.

tudinal movement of the rod, but when the i latter is rotated inone direction or the other by the handle 15 the ears'10 will be drawn inward to close the seats 9, or ,moved outward to open said seats, as will be appar.

through an ear l1 and then screwed into the adjacent car 10, and after the two parts are properly set they are rigidly coupled together by the split sleeve13. A very slight an ular movement of the controlling rod is sudlcient to open or close the two seats 9 simultaneously, said seats being at right angles to the carrier fulcrum 6. Thelatter is held in a heavy hub 16 which is inserted between the ears 5 so that no lateral move ment ofthe carrier is permitted, the casting constituting said carrier being made very rigid and stiff to insure accuracy; in the operation of the machine.

A transverse shaft 17 is rotatably supported in suitable bearings at the sides of the base 1, and as shown in Fig. 3 said shaft has an attached eccentric 18, the strap 19' thereof having an car 20 extended:

through an opening 21 in the top 2, and said ear is jointed at 22 to a bifurcated lug 23; depending from the cross plate 8 midway;

between its ends, Fig. 4. Every revolution of the shaft 17 will lower the carrier, as in Fig. 3, and elevate it, as in Fig. 2, and I provide any suitable one-revolution clutch device to operatively connect the shaft with a loose pulley 24 thereon, Fig. 1, and adapted in practice to be driven from any suitable of the pulley and shaft is indicated by the arrow in Fig. 2. The clutch therein illustrated is substantially the one shown and described in United States Patent No. 828,844, granted to C. A. Dahl August 14, 19 06. Briefly, the hub 9' having notch h and fast on the shaft 17, the clutch dog 9 having a tail-piece g to at times engage one of a series of pockets 3 in the interior of plate D bolted to the loose pulley 24; the spring k normally tending to effect engagement of the tail-piece g with a pocket 3"; the dog holder h fulcrumed on a stud it projecting from the side of the base 1; the link I? connected with a treadle or other manually-controlled device (not shown) and the other adjuncts of the clutch, are and may be all as in said patent.

When the dog holder 72. is in engagement with the dog 9 the tail-piece g is withheld from a pocket 3", and pawl k is moved by spring k to engage the notch h to prevent rebound of the hub g, and at such time the pulley 24 rotates but the shaft 17 is at rest.

To start the'machine the link 7& is drawn down to disengage the dog-holder h and dog 9 and immediately the spring 71. throws the tail-piece it into one of the pockets 3 and the shaft is rotated with the pulley.

having a portion 37 of its shank squared to The link k is released immediately after the clutch is thrown in, so that the dog 9 makes one revolution with the shaft and is then en'- gaged and stopped by the dog-holder b.

No further description of the clutch device or of the operation thereof is necessary to a proper understanding of my invention, as any suitable form ofonerevolution clutch can be used instead of. the one referred to.

Referring now to Fig. 8, a buttonhole strip is shown at W, and in such strip it is desired to make a series of 'buttonholes, for instance,'of a given' number and located at specified distances-from each other "and from the outer edge of "the strip, the position of the first buttonhole being indicated by dotted lines at 'w. p

By means now to be described aseries of buttonhole locations are indicated: on the strip, the locations being shown by the series of dots w".

The rocking carrier. '7, 8 has detachably connected with it a reversible. head, herein shown as a flat, rigid, and 'curved metal plate 25 having a segmental'slot 26 therein, and the concave edge of the head and slot are toward the front of the machine, as shown. Laterally separated cylindrical lugs 27 have each a widened and bifurcated front end 28 to receive ears 29 onthe'back of the head, suitable fastenings 30 rigidly connecting the parts, as best shown in Figs. 1 and 5.

; The'lugs 27 are in p'arallelism'and so spaced as to exactly enter the contractile seats 9 on source of power. The direction of rotation the carrier so that when the'seatsare closed the head is securely clamped "upon the carrier and moves as a unit therewith, said head extending forward to overhang more or less the work-bed 4 and to move toward andfrom it as the carrier is depressed and raised, respectively.

The head can be clamped either side up, as will be apparent, so that said head is reversible. The head carries a series of separate, independently adjustable marking members, each of such members being shown herein as comprising an elongated fiat and resilient metal finger 31, having a longitudinal slot 32 at its inner end and a hole 33, Fig. 10, near its outer end, and a .marking device, to be described, is carried by each finger. The slotted ends ofthe fingers are laid upon the head 25, crossing the slot 26 therein, so that the fingers project front- 12 ward more or less in radial directions, as shown in Fig. 1, and a retaining plate 34 is laid over the fingers, saidplate having a segmental slot 35 which registers with the head slot 26. A headed clampingbolt 36,

enter the slot 26, is passed through the superposed slots 26 and 35, and through the slot 32 of the finger interposed between the head and plate 34, and a nut 38 is then screwed onto the threaded end of the shank,

- so that when set up the finger is securely clamped to the head, a washer 39 preferably being interposed between the nut and the plate 34. The squared part 37 of the bolt clamping bolt. It will be seen that the clamping fingers are thus adjustable indi vidually in various'directions, so that their outer ends can be made to assume a line of any desired curvature, at desired distances from the head, and the front ends of said fingers may be separated from each other more or less, as required. So, too, any finger can he removed bodily from the head without disturbing: its fellows, whereby any requisite number and arrangement of marking devices can be used.

In the present embodiment of my invention each marking device comprises a conical or pointed head 40, preferably made of steel, havin a central, threaded shank 41 extende from the large end of the head, the end of said shank also being conical or pointed, at .42, Fig. 10, the points of the head and shank being alined with each other. Said pointed ends are at such a distance from each other that when the marking device is. fixed onits finger said points will be equally distant from opposite sides of the finger. The shank 41 is passed through the hole 33 in a finger 31 and a nut 43 is set up on the threaded shank, so that the marking device is securely clamped upon the finger, with a marking point at each side thereof.

The marking devices are adjusted conveniently by means of a gage or templet M, Fig. 9, of leather or other suitable material, having indicated thereon at m) the positions which the buttonholes, or buttons, are to have on the work. The gage is laid on the work-bed.4, the carrier is lowered, and the various fingers 31 are adjusted on thehead 25 until all of the marking devices register with the indices m" of the gage, and then the fingers are clamped in position. It will be manifest that when the work W is laid upon the work-bed 4 and the carrier is depressed the depending points of the series of marking devices will, as the head descends, impinge upon the work and form a series of slight pits or indentations w 'thereon, as indicated in Fig. 8. These marks indicate to the operator when the buttonholes are to be made, or where buttons are to be attached if the machine is used for marking button .locations. Now, if the machine is adjusted for a left stri as here shown, allthat is necessary for marking right f strips is to remove the head 25 from the carrier, turn it over, and replace it, so that while in the first instance the marking heads 40 marked the locations on lefts the reversal of the head will cause the pointed ends 42 of the shanks 41 to mark the locations on rights. Consequently, one setting ofthe marking mem hers is sufficient for rights and 'lefts by a simple reversal of the head 25 in the carrier, saving much time and labor. It is desirable to provide'meansto' positionthe edge of the work on the work-bed,

and as the marking devices are double-act? ing, as described, I have providddoubleacting edge-gages, andmount the same ad. justably on one or more of the fingers 31. An upright bracket 44, Fig. 6, isbifurcated at its upper and lower ends, at 45,.and, has-a central, laterally extended slotted ear 46,- Y

which is adapted to embrace a finger 31 and be held firmly thereon by a set screw 47.

In each of the bifurcated ends 45. I pivot at 48 an edge-gage 49, the longer arm. thereof extending outward toward the marking. de-

vices, and the shorter arms are connected by a spring 50, which tendsv to separate the longer arms.

As shown by dotted lines, Figs. 2 and 3,.

the bottoms of the bifurcated portions of Q the bracket are curved at 51 to serve as stops to limit the. separation of the longer arms of the gages.

When a bracket is clamped in desiredpc sition on a finger 31 the two gages 49. will be located at one side of said finger,.Fig.1 1,.

and above and belowthe same, Figs. 2 and 3, and the spring 51 will 881'"? to hold the free front end of the lower gage-against-thework-bed irrespective of the position of the carrier and head, so. that when they are raised, asin Fig. 2, the operatorcanslide the work W onto the work-bed untilit is positioned by engagement with the lower set of edge-gages 49. Now the clutch is thrown in, and the shaft 1"(,makes onerevolu-tion,

depressing the carrier and parts mounted thereon, so that the marking devices mark the work, and then the carrier and said devices are elevated as the machine stops.

When the carrier descends the lower or active gages 49 rock upon the work-'hed.-as shown by comparing Figs. 2 and 3, while still serving to position the work, and the upper or inactive gages are heldagainst the thus double-acting to accord with the reversible feature of the head and marking; devices.

The gages can be moved in or out along the fingers 31 which support the brackets 44,

rangement or spacing of the marking members, so that when occasion demands the operator will mount in the carrier the head adjusted or set for the work next tobe marked, thus obviating the delay attendant upon resetting any single head.
